But even today

This phrase refers to the time at which Paul was writing to the Corinthians.

whenever Moses is read

Here the word "Moses" refers to the Old Testament law. This can be stated in active form. Alternate translation: "whenever someone reads the Mosaic law" (See: rc://en/ta/man/jit/figs-metonymy and rc://en/ta/man/jit/figs-activepassive)

a veil covers their hearts

Here the word "hearts" represents what people think, and the people being unable to understand the old covenant is spoken of as if they have a veil that covers their hearts the way a physical veil would cover their eyes. Alternate translation: "they are unable to understand what they are hearing" (See: rc://en/ta/man/jit/figs-metonymy and rc://en/ta/man/jit/figs-metaphor)
